THREAD-GUIDE SUPPORT FOR SPINNING-MACHINES.

SPECIFICATION forming part Of Letters Patent No. 600,341, dated March 8, 1898.

Application filed July 1, 1895. Serial No. 554,575. (No model.)

To aZZ whom it may concern.-

Be it known that I, EDWARD WHITTUM, of Fall River, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Thread-Guide Supports for Spinning-Machines, of which the following is a specification.

This invention has for its object to provide certain improvements in the construction of the thread-guides of spinning-machines and supports therefor and to enable said guides and supports to be simultaneously displaced and held away from their operative position during the operation of doffing.

The invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents an end view of the roller-beam,showing my improved support and one form of mechanism for holding the said beam raised and depressed. Fig. 2 represents a top view of a part of the construction shown in Fig. 1. Figs. 3 and 4 represent views similar to Fig. 2, showing another form of mechanism embodying my invention. Fig. 5 represents a top view of the construction shown in Figs. 3 and 4. Fig. 6 represents a perspective view of my improved arm or holder for the thread-guide used as a substitute for the thread-block usually employed.

The same letters and numerals of reference indicate the same parts in all the figures.

In the drawings, a represents the rollerbeam of a spinning-machine to which my improvements are applied, and as said improvements relate entirely to the thread-guides b and their holders or supports and to the means for controlling the same I do not show the spindle-rail, ring-rail, spindles, separators, and other usual parts of the machine, these being unnecessary to a full understanding of my improvement. It is sufficient to remark that the thread-guides operate as usual in guiding the thread to the spindles.

Each thread-guide b is or may be made of wire, as usual, and is secured to a holder which is made of sheet-metal, preferably in a single piece, which is suitably treated to form, first, two ears 2 2, between which one end of the piece of wire forming the guide is clamped by the action of a screw or bolt 3, passing through said ears and pressing them firmly against the interposed portion of the wire, and, secondly, a socket 4, formed to embrace a rod or shaft 0, which is j ournaled in bearings upon the roller-beam and supports a series of holders b and guides Z). The arm I) is slotted at 19 between the ears 2 2 to increase the flexibility of said ears. The socket 4 is provided with a slot 5, into which projects a pin or screw 6, affixed to the shaft 0, said slot being of suflicent length to permit the arm I) to be raised sufficiently to permit the removal of the accompanying bobbin during the operation of doffing.

The shaft 0 is adapted to be turned in its bearings to simultaneously raise and depress the arms and thread-guides mounted thereon, the arrangement being such that the threadguides can be thrown downwardly behind the spindles, as shown in Fig. 4, during the operation of doffing the bobbins. I have provided means for looking or holding the shaft in either of the positions represented in Figs. 1 and 4 and thus holding the thread-guides either in their operative or displaced position. In Fig. 1 I show as the holding means a lever 16, pivoted at 17 to a support on the roller beam and having on one of its arms a weight 18, a link 15 connecting its other arm with an arm 14, affixed to the shaft 0. When the lever 16 is in the position shown in full lines in Fig. 1, it holds the thread-guides in their operative positions, the rotation of the shaft in the direction required to raise the threadguides being prevented by a stop device such as that hereinafter described in connection with Fig. 2. WVhen it is desired to doff the bobbins, the shaft 0 may be partially rotated by a lever or handle 19, such as that shown in Fig. 2 and presently described, to carry the arm 14 and with it the link 15 and lever 16 to the position shown in dotted lines in Fig. 1, the said arm 14 and link 15 being thus moved to such position that the weight 18 holds their meeting ends against the rollerbeam, thus holding the thread-guides in a depressed position. It will be seen that by moving the thread-guides downwardly and backwardly to locate them behind the bobbins during the doting operation I cause said guides to hold the thread in such position that it will naturally fall behind the bobbin,

the thread being thus disposed so that it is out of the way of the bobbin and does not come in contact with the hand that grasps the bobbin in the operation of doifing.

In Fig. 2 I show the shaft provided with an operating lever or handle 19, having a tooth 20, which engages a notch in a block 21, which is fitted to slide upon the shaft 0 and is pressed by a spring 22 against the tooth 20. Said block has an ear or lug 23, which is engaged with the roller-beam and prevents the block from turning. The block may have two recesses adapted to engage the tooth 20, one recess being arranged to receive the tooth when the shaft cis in position to raise the thread-guides and the other when the shaft is turned to depress the thread-guides.

In Figs. 3, 4, and Ishow an arm 28, pivoted at 27 to a support on the roller-beam and provided with a notch or recess 29, which engages a pin 30 on the arm 14, the latter being affixed to the shaft 0, as in the construction previously described. When the notch 29 is engaged with the pin 30, the shaft is held in position to operatively support the thread-guides. The arm 28is provided with a projection 33, arranged to-engage the pin 30 and hold the thread-guides in their displaced position. Said arm 28 may also be provided with a recess 34 near its outer end adapted to engage the pin 30 and support the shaft with the thread-guides raised above their operative position. In either construction the shaft 0 has an arm 14 affixed to it and an adjustable intermediate connection between said arm and the roller-beam, whereby the shaft may be held in difierent positions.

It will be observed that the sheet-metal arms I), bent from a single piece of sheet metal, constitute a very durable and economical substitute for the wooden blocks which are usually employed to support the thread-guides. It will also be seen that I substitute for the usual wooden thread-board the metal shaft 0, which is not liable to lose its proper shape, Whereas the ordinary wooden thread-board is liable to warp and thus cause permanent displacement of the thread-guides.

I have shown the arms I) provided with a bent-wire arm a, clamped between the cars 2 2 below the guide b, said arm being arranged to catch any knots or kinks that may appear on' the thread. Heretofore one end of the thread-guide has been extended downwardly from the loop or eye portion to constitutea knot-catcher; but by making the knotcatcher in a separate piece, as here shown, I secure an important advantage in that I am enabled to adjust the knot-catcher with reference to the thread-guide, such adjustment being often very desirable. v

I claim- 1. Ina spinning-frame, a shaft journaled in bearings on the roller-beam, a series of threadguide-carrying arms mounted on said shaft, means carried by said shaft for controlling the position of the shaft and arms on the axis of the shaft, and a yielding or movable looking connection between the said means and the roller-beam whereby the shaft and arms are automatically locked in raised or lowered position.

2. A thread-guide-carrying arm composed of a piece of sheet metal bent to form a shaftembracing socket, and a bifurcated arm provided with means for compressing the sides thereof upon the thread-guide.

3. A thread-guide-carrying arm composed of a single piece of sheet metal having the clamping-ears 2 2 and the shaft-embracing socket 4 having a slot 5, said ears having holes to receive a clamping-bolt.

4. In aspinning-frame, a shaft j ournaled in bearings on the roller-beam, a series of threadguide-carryin g arms mounted on said shaft, an arm 14 affixed to said shaft, a weighted lever pivoted to a fixed support, and a link 15 connecting said lever with the link 14, said lever, link, and arm being arranged so that the lever when in one position presses the thread-guides upwardly, and when in another position presses the thread guides downwardly.

5. In aspinning-frame, a shaft journaled in bearings on the roller-beam, a series of threadguide-carrying arms mounted on said shaft, an arm such as 14 affixed to said shaft, and a yielding supporting connection between the arm 14 and the roller-beam, whereby said arm, shaft, and thread-guides may be held in different positions.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 29th day of June, A. D. 1895.

EDWARD WHITTUM.
